ASH-SIFTER.

i Application led November 18, 1915.

.To all whom t may concern:

Be it known that I, FREDERICK W. Snrf MAN, a subject of the King of Great Britain,,

residing at Detroit, county of Wayne, State of Michigan, have invented a certain new and useful improvement in Ash-Sifters, and declare the following to be a full, clear, and exact description of the saine, such as will enable others skilled in the art to which it pertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification.

This invention relates to ash sifters and its primary object is an automatic ash sifter having two compartments and in which the ashes are sifted into one compartment and coal and clinlrers automatically delivered into the other compartment. A further object of the invention is a cheap and efficient device preventing the scattering of ashes and dust, thus providing a system that may be used either in the house as well as outside thereof without inconvenience. These and other objects of the invention and several novel features thereof are disclosed in the preferred form of the device shown in the accompanying drawings in whichw Figure 1 is a vertical section of an ash sifter embodying my invention showing the sifter in the position assumed when deliver ing coal and clinkers into one compartment.

Fig. 2 is an elevation partly' in section showing the sifter in position for sifting ashes into one of the compartments.

Fig. 3 is a cross section taken on line mmm of Fig. 2, showing the sieve and means `for supporting the same.

Fig. 4 is a detail of the hinge connection showing one of the rollers upon which the sieve is reciprocated.

Similar characters refer to similar parts throughout the drawing and specification.

The casing 1 is preferablv formed substantially cubical in form having a hinged door 2 on the top side thereof through which ashes may be placed in thensieve as hereinafter described. Hinged doors 3 and 4 are provided on one side of the apparatus through which material may be removed. The casing is divided into two compart` ments 6 and 7 by the sheet metal dividing wall 5 as indicated in Fig. 1, which wall is apertured at the upper end thereof to allow the sifter 8 to pass from one compartment into the other. rlhe sifter is box like in form, open on the upper side having the end Specification of Letters Patent.

members 9 and 10 and a bottom 11 hinged to the frame of the sieve as more particularly seen in Fig. 4. This bottom member 11 may be formed in any approved way preferably with a frame to which is secured a wire mesh of proper size for the purpose, as may be readily understood from the drawing. The side members l2 and 18 of the sifter extend beyond the end wall 10 as indicated in Figs. 1 and 2, and the sieve frame llalso extends beyond the said end wall when in closed relation as shown in Fig. 2, for the purpose hereinafter stated.

Mounted on the dividing wall 5 adjacent the aperture in which the sifter rides are two rollers 14, 14 indicated more clearly in Figs. 3 and 4, which .engage the bottom frame 11 and provide a roller for the sifter whereby it may easily be reciprocated. The sifter is provided with an operating rod 1G having a handle 17 at the outer part of the casing, the rod extending through an apen ture in the case and preferably through both the end walls 9 and 10 of the sifter as indicated in the drawings. The sifter preferably operates quite close to the top of the casing l and when in the position shown in Fig. 2, the hinged door 2 may be raised and ashes deposited in the sifter. By reciprocating the sifter in the compartment 6 the ashes will sift through the sieve bottom 11 into the said compartment and when the ashes have been separated from the clinkers and coal the said sifter may be moved forward into the compartment as indicated in Fig. 1, whereupon the hinged bottom 11 may fall as indicated by reason of the said bottom passing oil' from the rollers 14. As may be seen in Fig. 4 the hinged bottom 11 does not pass out of engagement with the roller but the hinged point of the said bottom in passing forward of the center of the roller allows the front end of the bottom to fall gradually whereupon material in the sifter rolls od from the bottom into the compartment 7. By this arrangement the ashes are delivered into one compartment and coal and such other lumpy material as is usually found in ashes is deposited in a separate compartment in which they may be conveniently removed through the doors 3 and 4 provided.

To assist in the sifting of the ashes and to shake the sifter in the compartment 6 the roller 14 on which the sieve bottom rides may have a knobby face as shown particukl1 is provided with a strip of sheet metal '23 at its forwardfend the purpose-of which 'is Yto prevent -a'sh dust-*from passing from compartment io linto compartment 7 when vthe sifter-8 is in position as shown in Fig. 2.

The sifter is preferably formed of Vsheet metal `and riveted together in any approved Vmanner with the proper flanges vor sti'i'iening` bars at'the corners but may be formed in an;v

" approved manner suitable for the purposer` ythe essential characteristic of which is the 4two compartments with the sitter adapted for vmovement from. one 'compartment into the other `for 'thepurpose stated.

Havinp; Athus `briefly described my yinvention, its utility, What I claim and desire to secure Vbv Letters Patent `of the United States iS- l. In an ash sifter, the combination of a Y suitable receptacle, of a partition dividingr the receptacle into two compartments, a

sitter reoiprocable Vin both compartments and shorter than each compartment. said srfter 'having a sieve bottom longer than the sifter, rollers mounted on the partition on which said bottom rides, the sieve frame being,- of suoli lengt-h that when the sitter '..s

moved into one compartment the bottom is held in closed relation therewith, and when moved into the other compartment falls by gravity as the hinged point of the sieve bottom passes beyond the Center of rotation of the rollers.

2; In an ash sifter, a receptacle, an apertnred vpartition 'dividing the receptacle into two compartments, a sifter reeiprocable in both compartments through the said apen ture, a hinged -bottom for the sitter formed of a foraminous portion equal in area to the area of the sitter and a nonforaminous portion extending beyond the end ot the sitter and side members extending beyond the end thereof, the said extension of the bottom and side walls in conjunction with said end of the sifterclosing the aperture to one oompartment when the sifter is drawn thercinto` and rollers mounted on the upper edge o' the partition on which vthe said hinged bottom rides, allowing the sieve bottom to fall by gravity on movement of the sitter into the other compartment to discharge the contents thereof.

In testimony whereof, I sign this speciication.
